Silex® HARD is a neutral pH formula utilizing proprietary chemically reactive hydrophilic technologies that allow the solution to penetrate deeply and enable self-sealing properties. As Silex® Hard is applied it immediately begins chemically reacting within the concrete’s matrix forming insoluble cementitious compounds that effectively self-seal micro pores and hairline cracks. These fast-reacting hydrophilic properties close off pathways for moisture from any direction, therefore allowing the concrete itself to become the water barrier; a hydrophobic surface.

*Due to the wide variety of substrates variations in concrete quality, porosity, job site conditions, temperatures and relative humidity will affect coverage rates and drying times.

Silex® HYDRO-HARD densifier is a proprietary formulation specifically designed using a hybrid technology that provides active protection properties that provides a depth of penetration up to 8mm deep into the slab while also producing a silica film wear layer on the surface of the concrete. Silex® Hydro-Hard chemically reacts with the silicate matrix within the capillaries and pores, forming bonds that provide excellent hydrophobicity while allowing it to remain breathable.

Silex® Hydro-Hard is a single spray-on-leave-on application, no rinse formula that enhances the durability and provides optimally protection against the absorption of water, moisture, and other aggressive substances along with forming a chloride intrusion barrier.
